SPECIFICATION forming a of Letters r tnt No. 610,686, dated September13, 1898.

Application filed October {1, 1S9'l. Serial No. 653,925. (No model.) i

To all whom it may concern:

Be it known that I, THOMAS H. MOONEY, a citizen of the United States,residing at Dayton, in the county of Montgomery and State of Ohio, haveinvented certain new and useful Improvements in Molds for Forming Tiles;and I do declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same, reference being hadto the accompanying drawings, and to the figures of reference markedthereon, which form a par-t of this specification.

This invention relates to improvements in frames for molds for formingtiles-such, for example, as mosaic tiles and to means for operating saidframes; and the said invention has for its object to provide a durableand light frame for vibrating the molds.

Referring to the annexed drawings, forming part of this application,Figure 1 is alongitudinal sectional elevation of the frame and molds.Fig. 1 is a side elevation. Fig. 2 is an end elevation of the same. Fig.3 is an elevation of the opposite end. Fig. 4 is a top plan view of aportion of the frame and molds. Fig. 5 is an enlarged elevation of thepitman, through which motion is transmitted to the frame. Fig. 6 is adetached side view of one of the plates connecting the two parts of thepitman.

The frame is mainly constructed of metalsuch, for example, as tubulariron, bar-iron, or angle-iron. In the present instance it is constructedof the latter material and comprises two side pieces 1, that standperpendieular at each end and curve upwardly from said end anddownwardly in the center at 2. These points 2 form the tilting points ofthe frame. 3 designates a series of uprights reaching from thehorizontal braces 4;. The latter connect the lower portions of theframe. The said uprights 3 have transverse braces between them andsupport at their upper ends the oblong rectangular frame 5,\vhichincloses a series of plates 6, that form the bottom of the molds inwhich the plastic or cementitious material is formed. The sides of themolds are formed by cross-pieces 7, which have their ends rabbeted inlongitudinal pieces 8, running lengthwise of the frame. A series oflifters are placed beneath the plates 6. These lifters comprise plates 9with downwardly-projected guide-flanges 10 and integral racks 11. Theplates 9 move in openings 12 in the bottom of the frame and are guidedin their movement by flanges 10.

13 designates cushions projecting from the plat-es 9 and upon which thebottom plates 6 of the molds rest.

14 designates a series of segmental gears fulcrumcd on a longitudinalshaft 15, suitably mounted in the frame. These segment-gears may beoperated individually by the handles 16,which project out to one side ofthe frame, or all of said gears may be operated simultaneously bydevices described as follows:

17 is a long bar lying across the upper sides of the handles 16. 18 areropes or cables connected to said bar and passing around winding-drums19. The said drums are tightly mounted on a longitudinal shaft 20,whichmay be rotated to turn said drums and wind and unwind the cables. Thewheel 20 on said shaft is rotated by a vertically-reciprocating rod 21,that moves in guides 22 011 the frame. The lower end of this rod restsin the teeth of the wheel 20, and movement is imparted to said wheel byactuating said rod in a manner presently described. The necessaryvibratory movement is imparted to the frame to cause the liquid orcementitious substance in the molds to settle properly around the piecesor marble or other similar substance with which said cementitioussubstance is united in forming the tiles. This motion is transmittedthrough a line-shaft 23, having a crank or eccentric thereon. The upperend of the pitman 25 is connected to said crank, and the lower end isdetachably connected to a hook 24 on one end of the frame.

During the operation of the apparatus it is important that some portionof the mechanism have a capacity for yielding or giving under theimpacts of the frame in order that breakage of the parts and anundesirable jarring be avoided. This yielding takes place at the pitman25,which consists of two parts, with a coil-spring 26 inclosed betweenthem. The ends of said pitman are yieldably connected by means of twoplates 27, which are loosely connected by bolts 28. The lower ends ofsaid plates are provided with oblong holes 29, that permit of a verticalmovement of said pitman independent of the rest of the mechanism and areturn of the parts to their proper position by the spring.

In operating the gearing to elevate the floors of the molds the lowerend of the pitman may be disconnected from the hook 24 and similarlyconnected to a hook 30 on the upper end of the reciprocating rod 21 andmotion thereby imparted to the shaft 20 to rotate the drums and drawdown the segmental gears 14.

31 is a foot-treadle pivoted on an end of the frame and serving to lockthe ratchet-wheel 2O against any movement backward.

Having fully described my invention, I claim- 1. In an apparatus formolding tiles, the combination of two continuous side pieces havingtheir opposite ends vertical, and their intermediate parts projecteddown to form the tilting points of the frame, transverse braces betweensaid side pieces, a series of uprights, aframe supported on saiduprights and carrying longitudinal pieces 8 and transverse pieces 7forming a series of molds thereon, a series of lifters movable in saidmolds, the said lifters each having a downwardlyextended rack, toothedsegments geared to said racks, and means for simultaneously actuatingsaid toothed segments, substantially as and for the purposes specified.

2. In an apparatus for molding tiles, the combination of a frame havingtwo side pieces 1 l the ends of which terminate vertically, and theintermediate parts of which project downwardly to form tilting points,longitudinal and transverse braces between said side pieces, a frame, aseries of uprights supporting said frame, and carrying longitudinalpieces 8 and transverse pieces 7 forming a series of molds thereon, aseries of lifters movable in said molds, each of said lifters havingdownwardly-projected guide-flanges 10 and a rack 11, a plate 6 carriedby each of said lifters, a series of segment-gears provided withoperating-handles and engaging with said racks, a bar lying across saidhandles, and means for operating said bar to simultaneously actuate saidsegment-gears, substantially as and for the purposes specified.

In testimony whereof I affix my signature in presence of two witnesses.

THOMAS H. MOONEY.
